TL;DR: The best AI voice changer apps for swapping singers include Moises, Lalal.ai, and Demucs, which effectively isolate vocals from instrumental tracks. To swap singers, extract the original vocal stem, process it through an AI voice conversion model, and mix the new voice back into the original instrumentation for a seamless result.
Creating a cover version of a song with a different singer’s voice is no longer limited to professional studios. Thanks to advances in artificial intelligence, you can now swap vocalists with surprising accuracy. This guide walks you through the process of using top-tier AI tools to transform any song into a personalized masterpiece.
Step 1: Choose Your AI Tool
The first critical step is selecting the right software. Moises is highly recommended for its user-friendly interface and excellent stem separation capabilities. It allows you to split songs into vocals, drums, bass, and other instruments with minimal effort. Alternatively, Lalal.ai offers superior quality for complex tracks, ensuring that the isolated vocals remain clear and free from background noise. For advanced users seeking full control, RVC (Retrieval-based Voice Conversion) models available on platforms like Discord or local installations provide the most realistic voice swaps, though they require more technical knowledge.
Step 2: Extract the Original Vocals
Upload your target song to your chosen platform. In Moises, simply drag and drop the audio file. The AI will analyze the waveform and separate the tracks. Download the vocal-only stem. This file contains only the singer’s voice, stripped of the music, which is essential for a clean swap. Ensure the audio format is compatible with your voice conversion software, typically WAV or MP3.
Step 3: Apply the New Voice
Now, take the isolated vocal track and input it into your voice conversion model. If using RVC, select a pre-trained voice model that matches your desired singer. Adjust the pitch shift settings carefully; most voice changers allow you to transpose the pitch to match the original key, ensuring the new voice fits naturally within the song. Process the audio, which may take a few minutes depending on the length of the song and your hardware.
Step 4: Mix and Finalize
Import the converted vocal track back into a Digital Audio Workstation (DAW) or a simple mixing app. Align it with the original instrumental stems you saved earlier. Add reverb and compression to blend the new voice with the music, masking any artificial artifacts. Export the final file and share your unique cover.
